what do "=&" / "&=" operators in php mean? where can I read info about them? searching google doesn't help
+16
A:
$a &= $b is short for $a = $a & $b which is the bitwise-and operator.
$a =& $b assigns $a as a reference to $b.
For more information, consult Google.

@hacker: Using a common name for the special character usually works well, e.g. "ampersand php".
